# 安裝 Java

### 一、下載 JDK

{% hint style="info" %}
Java 官網時常更新，因此看到的畫面有可能與以下教學有差異。

示範為下載 Java SE 8u102
{% endhint %}

進到[下載頁面](https://www.oracle.com/java/technologies/javase-downloads.html)，在Java SE Downloads 中Java Platform (JDK) 8u101 / 8u102\
點選DOWNLOAD。

點擊後會轉跳到下載頁面，此時找到想要下載的版本號(以下教學為8u102)， 點擊「Accept License Agreement」意指接受許可協議； 點擊後於下方選擇自己的電腦系統相對應位元版本進行下載。 (本教學以Windows x64 為主)。

點擊接受協議許可後則會出現\

之後在Download的地方點擊下載。
